## 🎯 Key Points

- Anduril has developed the Steelfin anti-aircraft missile family as an affordable replacement for PAC-3.
- The cost of the new missiles is potentially twice lower than existing analogues.
- Steelfin is compatible with Patriot M903A2, Mk 41, and Typhon launchers.
- Flight tests of the missiles are scheduled for 2027.

American defense company Anduril has officially introduced a new promising family of Steelfin anti-aircraft missiles, developed as an economical and mass alternative to the existing scarce PAC-3 missiles for Patriot air defense systems. The presentation of the innovative development has drawn immense attention from specialized experts and military analysts worldwide, as current realities deplete stockpiles of expensive Western air defense systems. ### Design Features and Steelfin Modularity

The concept of the Steelfin family is based on a two-stage architecture whose parameters can be flexibly and promptly adapted to perform specific combat tasks in the theater of operations. The first stage of the missile can be equipped with various solid-propellant boosters depending on the required flight range, flight performance characteristics, and the chosen launch method. The second stage is directly responsible for maneuvering and precise interception of an aerial or ballistic target. Meanwhile, all versions of the products use a single basic foundation: a unified hull, advanced avionics, embedded software, a modern flight control system, and standardized interaction interfaces.

### Production Efficiency and Manufacturing Scaling

The developers highlight a potentially twice lower cost compared to traditional heavy interceptors of a similar class as one of the main advantages of the new missile family, although the manufacturer keeps exact figures secret for now. The production process is planned to be organized on a single flexible assembly line with maximum use of shared equipment and unified components. At the initial stage, Anduril expects to assemble several thousand such missiles annually, with the capability of quickly scaling up production to meet customer demands.

### Launcher Compatibility and Testing Prospects

The newest anti-aircraft missiles were created with a view to maximum integration into existing allied land and naval air defense architectures. Full compatibility of the Steelfin family with Patriot M903A2 launchers, Mk 41 universal vertical launch ship systems, and the Typhon ground-based mobile missile system has been declared. Currently, the company has already successfully conducted a series of initial ballistic tests using experimental prototypes, with full-scale flight testing of combat modifications scheduled for 2027.
